Question

A sum of Rs 2000 becomes Rs 3645 in 2 years at a certain rate of compound interest. What will be the sum (in Rs) after 4 years?

A) 5942.125 B) 6643.0125 C) 7243.0125 D) 7498.125

Answer 1

Answer:

the interest in two years is = {(3645 - 2000) / 2000} × 100 = 1645/2000 × 100 = 82.25%

So, after four years the sum will be = 3645 + {3645 × 82.25/100} = 6643.0125 Rs.

So, the answer is B) 6643.0125
